Emissions of oil vapor and oil dripping from motors are caused by high pressure gases and oil leakages around the piston rings. This contaminates the engine and the environment. Crankcase ventilation systems provide a reduction of contaminants and protect the environment.

Most diesel engines today do have closed crankcase ventilation systems – where the gases are returned to the engine’s air intakes and the oil is returned to the engine pump. Open crankcase ventilation systems reduce contamination before the air is vented into the atmosphere.

We offer a wide range of filter elements for crankcase ventilation with brands like Fleetguard, MANN FILTER and Lekang.
